RESET MASTER during daily backups

[Russell Uman]

howdy.

we use the binary log as a crash recovery tool.
therefore, once we have backed up the db (we use the excellent mysql_backup for this) we
can happily discard yesterday's binlog.
the only correct way i've found to get rid of old binlogs in to issue RESET MASTER, and i
figure i should do this at the same time
that the logs get flushed.
however, neither mysqldump nor mysqladmin have a RESET MASTER option.
has anyone found a good way to do this?
